Aaron Collins died July 7, 2012, of unknown causes in a Lexington, Ky., hospital. After his death, his family found a will on his computer that included the following request:

"Leave an awesome tip. And I don’t mean 25%…I mean $500 on a … pizza…for a waiter or waitress."

Since then, Collins' older brother Seth and his family have been on a mission to fulfill that last wish.

After a video documenting the first tip went viral, donations poured in for Seth Collins to do it again... and again.

On Monday, nearly the one-year anniversary of his brother's death, Seth Collins gave away the 54th tip in Aaron's memory, according to ABCNews.com.

That $500 tip came at Thre3e Wise Men Brewing Company in Indianapolis, where server Beth Foster was overwhelmed at receiving the generous gesture.

"It couldn't have come at a better time in my life," Foster told ABC News' Indianapolis, affiliate WRTV. "I'm a teacher just looking for a job and it's kind of hard right now."

So far, the effort in his brother's name has collected $60,000 in donations and Seth Collins plans to visit all 50 states to give out $500 tips until all the money is gone. Monday's visit to Indiana represented the 17th state in his mission, with Seth chronicling each tip on his blog.
